This is likely one of the most difficult questions to answer in an interview. If you're asked why you left your most recent position and the primary motivator was that you disliked your boss, I would recommend that you do not mention that, but instead present your secondary motivation. From an employer's perspective, if you talk poorly of a previous manager, there's a risk that you may have issues with authority that may show up with any leadership over you. Just leave any negative comments about leadership out!
